I've only seen her movies Deewana but I still remember her.. She was also scheduled to star in Laadla with Anil Kapoor (Sridevi), Hulchul with Ajay Devgan (Kajol) and Mohra with Akshay Kumar (Raveen Tandon).. And some otherz..
There are many many rumours about cause of death.. Some people say that Sridevi was behind all this.. Divya was a threat to her.. People say she also resembled Sridevi in a way.. Other people claim it was her own husband Sajid Nadiadwala who also had connections with the underworld.. And some say it was suicide (I personally dont think it was suicide).. Still a mystery.. We'll never know..
Some people even claim that Om Shanti Om was made for a reason (Shahrukh's idea).. Re-birth.. Revenge etc etc.. Read about this at youtube.. dont really know what to think about that..!
Some people also said that it was some bad spirit who pushed her from her balcony :s and some say she was drunk and fell...many things said man..
